We used the `nnU-Net' architecture [1]} for automatic segmentation of CMR and echocardiography images in all frames through the cardiac cycle. In comparison to the standard U-net, the `nnU-Net' framework follows a holistic approach (topological parameters of the network architecture are automatically configured based on the training database) allowing for better generalisation. Figure REF  shows an overview of the `nnU-Net' networks used for CMR and echocardiography data.
